Bumper Question

My questions are; is it possible to replace my front bumper (gen 4 bull) to the front bumper of a gen 4 sable without any major fabrication? I would like to do this so I can have fog lights without having to jerry-rig it. Also I want to get dual exhaust when I get time/money, and was thinking of how cool the dual exhaust looks coming out of the gen3 sho, so same question is it possible without any major fabrication to replace my back bumper to that of a sho? Also how do you guys think this would look?
